Small Scale Wind Turbines
Wind power conversion has been around for so long that wind turbines are starting to look alike. One promising design is a helix coil that resembles a surface like a sail boat with the best angle to the wind turning the forward motion into rotational energy that can be harvested via high efficient generators. The simple design is very cost effective and ideal for remote island developments.

The one thing that is missing in the renewable energy equation is proper energy storage as most of the renewable technologies are unpredictable. A high density cheap storage solution will mature renewables overnight. There are promising cheaper safer options that address this problem where space not a restriction. Storage Technology sometimes needs a tailored solution that fit the load and energy charge available. Many Options are available to match the storage need. From small micro grids to large grid scale systems.
Organic Rankine Cycle turbines have been around for a while now, but recent developments in turbine technology, refrigerant mixtures and heat recovery cycles gave traditional efficiencies a major boost. Recovery can be as high as 20-25% from waste heat, competing with solar energy and the major benefit is that it is a 24/7 technology all year.
We live in a time where exciting new technologies are starting to reshape the energy landscape. Some of these are brand new and some are improvements on existing technologies due to new techniques and materials. Our edge is to keep a close eye on the trends and potentials of these technologies. Some of the promising technologies that are being tested or have already made it through the doors are:
Solar PV has a very good track record in the industry and it is normally the first technology to be implemented in the process to reduce the carbon footprint. Well established technology with steady decline in cost per kW installed.
We have access to a range of Solar PV technologies and well informed of advances in this field.
Wave energy harvesting solutions tend to use greenfield technologies that are always in research and development more. Tidal energy harvesting are taking off with many companies working on the next big thing. Tidal energy have fewer variation in the source making the solutions simpler.
